Overview
The MCR8NG is a reverse blocking thyristor (SCR) from onsemi, housed in a TO-220AB package. It features a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 8 A at 80°C case temperature. The device supports a high surge current capability of 80 A and operates within a junction temperature range of -40 to +125°C. Electrical characteristics include a gate trigger current maximum of 15 mA and a critical rate of rise of off-state voltage of 100 V/µs minimum.
Feature Summary
- Glass passivated junctions for reliability and uniformity
- High immunity to dv/dt with specified minimum values
- Specified minimum and maximum values for IGT, VGT, and IH for ease of design
Applications
- Half-wave AC control applications
- Motor controls
- Heating controls
- Power supplies
Procurement Notes
Verify the specific part number suffix against official datasheets to confirm package type and lead-free status. Ensure thermal management aligns with the specified junction-to-case resistance. Confirm that application conditions do not exceed the absolute maximum ratings for voltage, current, or power dissipation.
Selection Notes
Select this component for half-wave AC control circuits requiring robust surge handling. Consider the 8 A RMS rating and 600 V blocking voltage for appropriate load matching. Evaluate thermal requirements based on the specified case temperature limits and ambient operating conditions.
